SPECIFICATION forming part of Letters Patent No. 657,300, dated September 4,1900.

7 a plication filed May 23. 1 900.

I To aZZ whom it may concern f Be it known that; I, FRANK summer Lawrence, in the county of Essex and-State of Massachusetts,ha' ve invented certain newand useful Improvements in Pneumatic Clot-h Flnishing Machines, of which the. following is a specification.

This invention relates to machinesfor extractin g water from fabrics in which the fabric is spread or stretched and subjected to the action of a suction apparatuswhich draws the water through'the back side of the fabric 1 1 ing of the dye or coloring-matter with which and carries the water away from the face or right side thereof, so that the face is prevented from bein g clouded or streaked by the bleedthe body and backing of the fabric is impregnated.

The invention has for its objects to provide a machine of this character. adapted to more efiectively extract water in the manner described than heretofore and also to provide a machine which can be used, "if desired, for applying liquid to the face side of the fabric and drawing the same liquid through the fabric and from the backside, leaving the fabric slightly and uniformly dampened either as a preparation for pressing or to sponge and shrink the fabric before it is cut and made up. 7 7

The invention consists in the improvements hereinfter set forth and claimed.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of a machine embodying my invention. Fig. 2 represents a longitudinal vertical section of the same. Fig. 3 representsa section on line 3 3fof Fig. 2, showing also a side elevation of the suctionpump. Fig. 4 representsan enlargementof a portion of Fig. 3; Fig. 5 represents aside elevation of parts of the machine. Fig. 6 rep resents an elevation showing parts of the tension device shown in Fig. 2. Fig. 7 represents a section on line 7 7 of Fig. 6.

The same reference charactersindicate the same parts in all the figures.

In the drawings, 1 represents the frame of the machine, which may be of any suitable form and construction.

2 2 represent suction pipes or beds, of which two are shown, these being supported side by SerialITo.18,245. (NomodeL) side on theframe and connected by a branched. coupling-sections with a conduit 5, which is connected with a pump 6, adapted to draw air and liquid through the suctionpipes 2 2. Said pipes have slots 7 7 in their upper portions, over which the piece of fabric 8 to befinished is drawn under tension, as hereinafter described. Above the suctionpipes 2 2 arerubber-covered rolls 9 9, which bear on the upper or face side of the piece 8' and prevent the free admission of air to the slots 7 through-the intermediate fabric, the

.rubber coverings of the rolls being sufiiciently elastic to cause their under sides to flatten when they bear on the fabric, and thus obstruct the passage of air through the fabric,

the rolls at the same time squeezing the water l from the fabric and facilitatingits withdrawal th ough theslots 7.

1O lOrepresent sprinkler-pipes which are located above the suction-pipes and are connected with a source of water-supply and provided with perforations arranged to deliver waterin numeroussmall streams 100 on the fabric at points close to the pipes 2 and rolls 9, the fabric being thus saturated or dampened, if desired, just before it passes over the slots of the suction-pipes. If this saturation is not desired, movable troughs 12 12, supported by swinging arms 13 13, may be moved bymeans of a handle 14: into position to catch the water discharged by. the pipeslO, said troughs being provided with flexible outletpipes 15, discharging into a pan16, affixed to the frame 1. Said pan is arranged to also receive any water that may fall from the external surfaces of the suction-pipes and has a waste-pipe 17. The fabric enters the machine between tension-bars 18 l8,which are attached to arms 19 19, having trunnions 20. Said trunnions are locked with the arms 19 at any desired angle by means of disks 21, Fig. 7, affixed to the trunnions, and frictional clamps 22 22, surrounding said disks and hinged at 23 to fixed arms 24 on the frame 1. A screw 25 in the outer ends of the. clamps tightens theclamps on the disks 21, thus locking the arms 19 and tension-bars 18.

From the tension-bars the fabric passes over a guide-roll 26 and from thencedownwardly to a guide-roll 27, a vertical stretch of the fabric being thus subjected to the action of a rotar'y brush 28,whichbrushesthe'back side of the fabric. Guiden'olls 29 30 present another .verticalstietch of the fabric toanother'rota'ry brush 31, whichjacts on the face side' of-thej "fabric Unde'rithe brushes 28 nagram;

45 in said brackets, the latter jhaving bearings for the =journals of the guide:- rolls. a The,

. brushes 28 and f3l are drivenby a belt 46, Fig! i 2,-running-ona, pulley 47 on the driving-"shaft" and-onif-pulleysZ on the brush-shafts; TI

The suctiqfl pipesflfl are preferably p I .videdlwith airinlets 48,- Fig. 3, which may ie closed byvalves49,adapted tobe'simultane-f tions 51,52.- C 3 5 ously operated by the leve'r' fvO and, connem (ShownfinFig. 5.) These'valves may beadjustedfto prevent the admission' of airto the suction-pipes or to permit more or lessair to enter j the same, thus varying the force with which wateris drawn from the fab a ric. by the action of the pump I .40

The sprinkler-pipes- 10 1.0 are'connected' with a water-supplypipe 54 by the branches a 55' 55 and the intermediate connections 56 57.

7 (Shown in Figs; 1 and 3.) A steam-pipe 58 I admits steam to thewater at a point between the branches 55 55-for,thepurpose of heating lth'e'water, if desired.

Each suction-pipe 2 is provided with a valve or gate 59, whereby either pipe may be shut off from the pump. Valves 6O 60 are pro- Vided, whereby water maybe shut ofif from either of the sprinkler-pipes 10. Pressuregages 61 are connected with the pipes which I supply the sprinkler-pipes 10, and a pressuregage 62 is connected with the suction-conduit 5. p v r Each of the sprinkler-pipes 10 has a swab 63, attached to a handle 64, which is movable through a stuffing-box 65 at one end of the sprinkler-pipe. The swab is of such diameter that it closely fits the perforated portion of the sprinkler-pipe and removes any sediment which may accumulate therein, thus preventingthe obstruction of the perforations. 9 It will be seen that the sprinkler pipe or pipes arranged to deposit water on the face side of the fabric, so that it will be drawn 'clare, that whatI-claimis-e 'through: the fabric and; from 5 the back side thereof bythe suction apparatus,.enahles the ,machinetobeused for dampening'fabric introducedin adry condition into the machine, the 'wa'ter beiing forced into thefabric; by the i -.rubbe'r -'.c overed. roll or; rolls and, drawn through the fabric "at d jf fr'oj'm the; backside ftheieof by "the suction} apparatus.
